The TS 900 C pocket transmitter with charging contacts has been designed for multifunctional applications especially for broadcast applications or in fixed installations.

Using the ACT infra red interface the selected frequency can be transmitted from the receiver to the transmitter. The LC-Display clearly indicates the selected channel/group and the battery status (5-stage). The 4-pin mini XLRStandard connection of all beyerdynamic pocket transmitters. All beyerdynamic microphones with .18 connectors can be used, e.g. Opus 54.18, MCE 60.18, etc.input connector is utilized for the connection of microphones or instruments. For a great number of microphones and instruments the signals can be matched to an optimum level by using the gain control. With the MT-/GT-switch it is possible to select between microphones and instruments. In the GT-mode (GT for guitar) the gain control is inactive, in the MT-mode it is active.
